Non-Newtonian corrections to radiative viscosity: Israel-Stewart theory as a viscosity limiter
Lorenzo Gavassino
Radiation is a universal friction-increasing agent. When two fluid layers are in relative motion, the inevitable exchange of radiation between such layers gives rise to an effectiv…
Convergence of the hydrodynamic gradient expansion in relativistic kinetic theory
Lorenzo Gavassino
We rigorously prove that, in any relativistic kinetic theory whose non-hydrodynamic sector has a finite gap, the Taylor series of all hydrodynamic dispersion relations has a finite…
Modelling stochastic fluctuations in relativistic kinetic theory
Gabriel Soares Rocha, Lorenzo Gavassino, Nicki Mullins
Using the information current, we develop a Lorentz-covariant framework for modeling equilibrium fluctuations in relativistic kinetic theory in the grand-canonical ensemble. The re…
Analytical insights into the interplay of momentum, multiplicity and the speed of sound in heavy-ion collisions
Gabriel Soares Rocha, Lorenzo Gavassino, Mayank Singh +1
We introduce a minimal model of ultracentral heavy-ion collisions to study the relation between the speed of sound of the produced plasma and the final particles' energy and multip…
Gapless non-hydrodynamic modes in relativistic kinetic theory
Lorenzo Gavassino
We provide rigorous criteria to determine whether the non-hydrodynamic sector of a relativistic kinetic theory is gapless. These general criteria apply to both Boltzmann's equation…
Causal and Stable Relativistic Hydrodynamic Fluctuations
Nicki Mullins, Mauricio Hippert, Jorge Noronha +1
When two nuclei collide close to the speed of light, a fluid state known as the quark-gluon plasma is formed. Attempts to understand the dynamics of this fluid have generated signi…
